lie it known that l. XiiLs H. HASSEL, a citizen ol' the l`nited States. residing aty Los Angeles. in the county ot' Los Angeles :ind State oi'(`alit'ornia. hare invented a new and uscl'ul livetiiig Device. ot which the following is a speciticatioii.

.\l urcntion relates to the art oi' riveting, hciiig more particularlr a rivetingtool which is .supported and iiiagneticalliY held against. thc plates in .such `i iiianlici as to take up or cushion the jai' of the tool during the rivet:4 ing operation. ln handling riveting tools the jar or impact ot' the tool is coiiiniuni cated directly to the operator to such an extent that `such work' is very tatiguing to ihc operator and eventually results in dis- :ihleinciit ot' the operator t'or such work.

Yl`he principal ohject ot' in r invention is to produce a riveting device ot' :siinpli` torni and construction. in which the riveting tool proper is suspended or nioiiiited elasticallr iii a support. which during the riveting operation is niagneticallv held against the plates upon which the work is heilig pppt'oruied.

(thci ohjccts and advantages will appear hcreinat'tcr t'roni the following spccitication.

ltcteri'iiig to the drawings. which are tor illustrative purposes onl'v.

Figure l is a side elevation oi' the device. partly iii section, cliihod \ilig a torni of ni-\' invention.

lf' 2 is a l'ace view ol the device shown l. :intl

Vig. il is a general i'iew ot the device. .showinf r a huckiiig tool iiioiiiited iii the .support instead otI the riveting tool proper.

l1 designates :i riveting tool having a hod)v l2. :i handle lil. and a haiiiinel 1t. ln the t'orni shown the tool is ot the pneuinatie Irvpe hcingsupplied with air under preasure through a llexihle connection indicated at 1.3, siicli` aii pressure heilig controlled as is usually done hva lever indicated at lti. The riveting tool is Isupported in a vokc. the hody 1; olI the tool extending through a circular opening 1T tornied in a collar 1S. which collail has l'orincd thereon two ariiis 1S) which extend out\\':\i'dl and forwardly fi'oiii the collar. each terminating in a t'oot 2U. llach l'oot tt is segmental in shape as shown in Fig. 2 :iiirl is hollowcd out or recessed to l'orni a pocket il to receive a winding 22 which is arranged ahoiit a core "lil, the feet forming eleetro-magnets for the purposes hereinafter descrihed.

Each leg 1S) of the yoke is hollow aS indicated at 25 through which extend wires 2U and 2T t'roiii the respective windings '.)L to a socket 2H supported on one ot' thel arms lt). rl`he. socket 2H is adapted to receive a plug 2S) as diagraniiiiatically shown in Fig. l, the plug- 2.) heing` connected through wires It() and 3l to a suitable electro power Source, a switch 32 heing provided on the handle 13, preterahli1 on the inside ot' the handle as indicated in Fig. l for the purposey ot' closing the electro circuit to ina-ke. the electro magnets in the arnis 19 active for the purposes hereinafter described.

The outer end otl the hodv 12 of the rivet.- ing tool is threaded as indicated at 3i upon which is threaded a nut held in plaee by nieans ot' a lock nut 3G. nterposed between the nut 35 and the. outer side of the collar 1S is a coiled compression Spring 37, a circular flange BS heing formed on the outer side of the end otl the spring engaging the collar and preventingdislodginent of the saine during the operation of the riveting tool. it) and tl designate two plates upon which the work is heing pcvt'orined` 4'.) a rivet and t8 a huele.` ing` tool held against the plateI on the oppo site side ot' the saine to the lianinier 1t.

1n the t'oriii shown in Fig. 3 the `yoke is used for the purpose ot' supporting the huckiiig tool. it heilig understood that the yoke constri'icted as ahove descrihed nia \`v also he used tor supporting the hackingT tool and thereinv reducing or ahsorhing the inipaet ordinarily received h v the buckingl tool during the operation ot' riveting.

The device ahoi'e deserihed operates in the following inanner:

'hen a rivet is to he headed the. riveting tool is placed in position with the haininer over the rire-t and with the t'eet 2t) resting against the plates to he riveted. The switch :52 is then closed and the feet hecoiiie niagnetized a .siuliicientl degree to hohl the yoke tiriiil against the plates during the rivetiiiig operation. The air is then admitted to the tool hy operation olI the lever'lt and the riveting action takes place, theI tool heiiig held againsty the riret h v the person opi-rat;- ing the device, hut the tool heilig held or supported on the spring 3T. The, shocks caused h v the iiiipact ot' the, haniiiiei' it are collar ISto forni a seat for the Vl t) (l iii.-

absorbed to :i large extent by the spring 3? thereby relieving' the operator trom the lori-o ol' lh(i shoi'li's whirh :ire ordinati-ily dil' ll lii'oivid h y the person holding: the lool,

lt is lo lio noli'd lhut ronsidnl'uhh .spare is lzl't between thil body of lhi` riveting tool :ind the inside ol` the rollin' 1H so that the tool m:1 he moved (o ndjnst the yeine withont removing the volte l'rom tb jointe.

`When the rivetingy operutionibns been linished the nir is .shut oli', the riveting netion boing stopped. the switch 3:2 is opened und thil .voltimuy be readily detached from the plete und moved into position for t-lie next` rivet.

l claim us my invention z- 1. A riveting deviee consisting of a supporting member, n rivetinlgr tool extending l'reely through and elnstiezilly supported in the supporting member, and menns whereby snid supportingr member is elertro-mngnetiwilly held ngninst the work during tbe ri vetin,, r operntion.

:2. A riveting device comprising' e snpporting devirr consisting ot' n ring, legs formed on snid ring. n coil in the end ot oni-h leg:` n riveting,r lool extending),r treelj.,Y

moenee posed between seid nut and seid supporting e member.

4. A riveting device arranged to absorb shocks comprising e supporting member, legs on seid supporting member, e coil in the end of each leg, means for energizing seid coils, u riveting tool extending freely through a central opening in the supporting member, n removable abutment on the inner end of the tool, and a coiled spring about seid tool interposed between said abutment eind the supporting member.

In testimony whereof, I have hereunto set my lnmd at' Los Angeles, Californie, this 13th dey of June, 1918.
